73 Magazine (Amateur Radio Today)

73 Magazine (also known as 73 Amateur Radio Today) (OCLC 22239204) was a United States-based amateur radio magazine that was published from 1960 to 2003. It was known for its strong emphasis on technical articles and for the lengthy editorials in each issue by its founder and publisher, Wayne Green. The magazine title, 73, means "best regards" in amateur radio lingo. Green, a former editor of CQ Amateur Radio magazine, published the first issue of 73 in October 1960.

At that time, the magazine was headquartered in Brooklyn, New York. Among contributing editors was author and radio personality Jean Shepherd, K2ORS. The magazine was a pioneer promoter of SSB, FM, solid-state, easy construction projects, and the marriage of personal computing and amateur radio. His interest in microcomputing led Green to found several of the early personal computing magazines, including "Desktop Computing", Kilobaud Microcomputing, and 80 Micro, among others. Green was involved in the founding of Byte Magazine, another early and influential microcomputer magazine, later published by his wife, Virginia Londner Green. Since the summer of 1962, 73 was based in Peterborough, New Hampshire. At the peak of its popularity in the 1970s and 1980s, individual issues of 73 totaled more than 300 pages of advertisements, articles and commentary. Heading each issue was Green's editorial column, "Never Say Die", in which he often criticized the American Radio Relay League and his magazine's competitors for their perceived shortcomings. The title "Never Say Die" was a backronym for Green's amateur radio call sign, W2NSD.

After completing 43 years of publication, 73 Amateur Radio Today magazine ceased publication in October 2003. Publisher Wayne Green cited financial pressure from reduced advertising revenue as the prime reason for shutting down publication of the magazine.
